Iíve been waiting for someone with computer skills to respond. No luck so far.

You will need to download Sudoku Susser. Then:

(1) Right click on the Decabit puzzle, Select All and copy to the system clipboard.
(2) Paste into a word processing program, select the grid alone and copy to the clipboard.
(3) Paste into Sudoku Susser and save the puzzle when Susser has finished analysing it.

When you open the saved puzzle, you will find a grid you can use elsewhere.
